MeCP
MeCP is one place to store everything about you, and a way to plug that context into any AI app,
Project Description
One vault for all your context. Everything about you — how you communicate, what you're working on, your values, your preferences — stored in one place you own, organized into facets.
Plug into any app, once. Connect MeCP to Claude, ChatGPT, or any AI tool. It knows you instantly. Switch tools tomorrow — your context comes with you, not the app.
You choose what each app sees. Yelp gets your dietary preferences, not your health data. Claude gets your communication style, not your finances. Set it, change it, revoke it — per app, per facet.
Share your expertise — and get paid for it. Grant part of your vault to a business so their AI can use your knowledge. Your taste becomes a product; your identity stays yours.
See it all in Constellation. A spatial interface where each facet of you is a node you can navigate, configure, and extend to the apps in your life.
How it's Made
We used Expo / React Native (+ react-native-web), Convex (backend + DB), Tamagui (UI), LangGraph (agent), Model Context Protocol (MCP server), Three.js (the 3D constellation embed). pnpm monorepo, TypeScript.
One Expo app (UI) talks to Convex (data + server routes). Two workspace packages extend it: packages/mecp-agent (LangGraph agent) and packages/mecp-mcp (MCP server that exposes your context to AI clients like ChatGPT). The 3D view is a self-contained HTML/Three.js file loaded in a WebView/iframe.
